Many avid users of the Google wave collaboration tool were disappointed when they found this service was obviously not one of those services that Google cares about, but was announced to be shut down at the end of the year. While some alternatives for business collaboration exist, many projects were already deeply using wave and therefore reluctant to move the data over to another system.

So, many will be happy to read that Google has announced to give wave a second life as full open source project: In the coming months, the company will open-source a combination of the server and a client, with the server having persistent wave store and search functionality (first of which is heavily desired; they will use the same backend as crealytics, that is MongoDB).

The newest developments will be published in the Google Wave Federation Protocol discussion forum.
